StructPassing: do not transform arguments to annotation built-ins
Make sure struct/union arguments to __builtin_annot and related
builtins are always passed by reference using the default passing mode,
regardless of the ABI for passing struct/unions to "real" functions.
This ensures portability of annotations across ABIs, and avoids mismatches
between the annotation text and the actual number of arguments
(when a struct/union argument is passed as N integer arguments).
A similar special case already existed for __builtin_va_arg.
